F Ball - Stopgap 460 Exterior (10kg) Rapid Repair Compound for Floors

STOPGAP 460 is a polymer modified, fast setting mortar for repairing external floors prior to the application of STOPGAP 850 or for use in internal applications under STOPGAP waterproof surface membranes. It has been specifically designed for use in damp conditions and has excellent freeze / thaw resistance when used in external environments. 

STOPGAP 460 can be used for the non-structural repair of lower strength concrete elements such as floor screeds, concrete paving slabs, balcony edges, stair treads and risers and is also suitable for producing gradients for ramps. 

STOPGAP 460 is dimensionally stable and is supplied as a pre-blended dry powder designed for applications between 3-50mm. It is protein-free which allows it to be used in biologically sensitive areas. STOPGAP 460 is suitable for use with sand/cement screeds and concrete and under STOPGAP waterproof surface membranes.

Technical Information:

  • Appearance: 10kg plastic bucket
  • Consumption per mm thickness:1.43 kg/m²
  • Working Time @ 20°C: 10 – 15 minutes
  • Walk on hardness time @ 20°C: 60 minutes
  • Application thickness: from 2 - 50mm
  • Ready for covering: 24 hours



A 10kg bucket of STOPGAP 460 mixed with 2.6 litres of clean water will cover approximately 0.7m2 at a thickness of 10mm. Note: Coverage rates will depend on the condition and absorbency of the subfloor


Trowel the mix onto the subfloor and spread to the required thickness ensuring good compaction to the existing profile at time of placing. For increased economy, with applications of more than 10mm, the filled mix can be used. If required the finish of the mortar can be improved by the use of a wet smoothing trowel or damp sponge before the mortar has fully set, typically 15 to 20 minutes at 20ºC. When being applied in external applications, protect the repair area from rain, wind and direct sunshine whilst curing.

For any areas under question please consult the F Ball Technical team.


The initial set time of the repair compound is approximately 60 minutes at 20ºC and can accept light foot traffic after this time. Lower temperatures will extend this time i.e. at 10ºC set time will be approximately 2 hours. When STOPGAP 460 is applied beneath STOPGAP 850 Exterior or a STOPGAP waterproof surface membrane the mortar should be left for 24 hours before overcoating.


Suitable steel smoothing trowel, spiked roller, mixing bucket, electric drill and power whisk. Wash tools with water immediately after use.


This product must be stored under cover, in unopened bags clear of the ground in cool dry conditions, protected from frost and excessive draught.

Shelf Life:

9 months in unopened buckets and stored under good conditions.
